Description
Creates a note in a PDF document. Notes in PDF documents are the PDF equivalent of sticky notes and can be used to add comments and small items of information to a document.
The size of the note is determined by the bounding box starting at the lower left coordinates llx , lly and ending at the upper right coordinates urx , ury . text sets the textual content of the note, while title is the text that appears in the title bar when the note is opened.
If mode is specified, coordinates are calculated in PostScript points. There are usually 72 PostScript points to an inch. If not specified or set to 0, then the pages default units are used.
